Compilation of graphs from the organization, showing the overall global percentages of the last two centuries, in six factors: Extreme poverty, democracy, basic education, vaccination, literacy, child mortality.

Our World in Data (OWID) is a scientific online publication that focusses on large global problems such as poverty, disease, hunger, climate change, war, existential risks, and inequality.[1]

The publication's founder is the social historian and development economist Max Roser. The research team is based at the University of Oxford.[2]



The mission of Our World in Data is to present "research and data to make progress against the world’s largest problems".[3]

The web publication on global development uses interactive data visualisations (charts and maps) to present the research findings on development that explain the causes and consequences of the observed changes. The aim is to show how the world is changing and why. Infographics of Our World in Data, shared by Bill Gates in early 2019, show the history of human progress over the past 200 years.[4]

Our World in Data covers a wide range of topics across many academic disciplines: Trends in health, food provision, the growth and distribution of incomes, violence, rights, wars, culture, energy use, education, and environmental changes are empirically analysed and visualised in this web publication.

It often takes a long-term view to show how global living conditions have changed over the last centuries.

Covering all of these aspects in one resource makes it possible to understand how the observed long-run trends are interlinked. The research on global development is presented to the audience of interested readers, journalists, academics, and policy people. The articles cross-reference each other to make it possible for the reader to learn about the drivers of the observed long-run trends. For each topic the quality of the data is discussed and, by pointing the visitor to the sources, this website works as a database of databases – a meta-database.[5]

Publishing modelEdit

Our World in Data is one of the largest scientific open-access publications. It is made available as a public good:

  • The entire publication is freely available.
  • All data published on the website is available for download.
  • All visualizations created for the web publication are made available under a Creative Commons license.
  • And all tools developed to publish Our World in Data and to create the visualizations are free to use (available open source on GitHub).[6]

Collaborations and partnershipsEdit

The Our World in Data team partnered with several organizations:

The publication has been funded by grants from the Bill and Melinda Gates Foundation and the Nuffield Foundation as well as donations from hundreds of individuals.[7]

The research team is based at the University of Oxford's Oxford Martin School. Director is the founder Max Roser.[8]

In early 2019, Our World in Data was one of only 3 nonprofit organizations in Y Combinator's Winter 2019 cohort.[9][10]

The Our World in Data research team also publishes their research work in a number of widely accessed media outlets including the BBC,[11] Vox, the New York Times, the Guardian, and the Washington Post. The research team has also collaborated with science YouTube channel Kurz Gesagt and reached millions of viewers.


Research from Our World in Data is used in many ways:

The website is used widely in the media.[12] The BBC and publications like The Washington Post, The New York Times, and The Economist regularly rely on Our World in Data as a source.[13][14]

Tina Rosenberg emphasised in The New York Times that Our World in Data presents a “big picture that’s an important counterpoint to the constant barrage of negative world news”. Steven Pinker placed Roser’s Our World in Data on his list of his personal “cultural highlights”[15] and explained in his article on 'the most interesting recent scientific news' why he considers Our World in Data so very important.[16]

Private sector companies, like McKinsey Consulting, rely on Our World in Data publications to understand emerging markets and changes in poverty and prosperity.[17][18]

Authors like John Green and Steven Berlin Johnson use it for their work.

Our World in Data is used by teachers and lecturers in a range of subjects including medicine, psychology, biology, sustainable development, economics, history, politics and public policy. Institutions that rely on this online publication for their teaching include Harvard, the University of Oxford, Stanford University, the University of Chicago, The University of Cambridge, and the University of California Berkeley.[19]

Our World in Data is cited in academic scientific journals like Science,[20] Nature,[21][22][23] and PNAS (Proceedings of the National Academy of Sciences);[24] in academic journals focusing on medicine and global health like British Medical Journal[25] or The Lancet[26] and in social science journals like the Quarterly Journal of Economics.[27]
